QUICK-ACTIN G MULTIPLE-PURPOSE IMPLEMENT.

and State of Virginia, have invented certain new and useful improvementsin Quick-Acting Multiple-Purpose Implements, of which the following-is aspecification.

This invention relates to quick acting multiple purpose implement, andhas for its object to provide a hand implement or tool adapted for usefor various purposes, such as a wrench for nuts or pipes, a shear, a orfor various other purposes where great stress in limited space isrequired.

A further object of the -invention is to provide an organization havinga great range of adjusta-bility, with movable jaws and means forapplying a great degree of stress to the jaws by the application ofmanual power to the levers.

A further object of the invention is to provide a device havinginterchangeable jaws and parts'whereby the implement, as an entiret maybe quickly, and conveniently changed from performing one utility toanother.

With these and other objects in view, the device comprises certain novelunits, elements, parts, combinations, vmechanical movements andfunctions as will be hereinafter more fully described and claimed.

In the drawings Figure 1 is a. view of one embodiment of the inventionshown in section.

tion shown in section, the jaws showing in dotted llnes its utility as apipe wrench.

, Like characters of reference indicate corresponding parts throughoutthe several views.

In the type of implement shown at Figures 1 and 2, the body portioncomprise side plates 10 and 11, which are preferably, though notnecessarily, joined in a unitarv structure by a cross bar 12. To thisbody, comprising the side bars-1O and 11, a hans $113, 13, 1s securedrigidly but adjustably.

e of a rosette connection shown at 14 in Figure 2, nuts 15 and 16mountedupon the pintle 17, which pintle rotates in the body and carriestherewith the nuts 15 and 16, but the compremion of the nuts upon thehandle 13 by reason of the rosette joint maintains such handle in rigidconnection with the body.

Between the side bars 10 and 11 a jaw member 18 is removably secured bythe bolts 19 and 20,-whereby the said jaw member 18 may be removed andreplaced by a jaw for a different purpose.

The pintle 17 extending as it does through the side bars 10 and 11, isprovided at the side opposite the handle 13 with the lever 21 connectedto the pintle by a rosette joint 22, a nut 23 being employed for securmgthe necessary compression. Between the side bars 10 and 11 a link 24 isrigidly secured to the pintle 17 in any approved manner as by the" keys25 formmg wlt-h the lever 21 an adjustable bellcrank lever. This link ispreferably of channel formation as indicated by the web 26 in Figure 1,,but it is to be understood that the link is not limited to such channelstructure.

The link 24 is provided with a pintle 27 upon which is pivoted a pawl28. The pawl 28 is provided with a nose 29 proportioned and positionedto engage the rack 30 of the slidable relative to the side bars 10 and11 by the tongued and grooved formation indicated at 32.

A spring 33-is secured between the side bars 10 and 11, and has its end34 bearing under the web 26 of the link 24, tending to raise such linkfrom the position shown at Figure 1. A spring 35 is also secured betweenthe side bars 10 and ll and bears upon the pawl 28. The pawl 28 isprovided adjustability is accomplished by meanswith a finger 36positioned to engage a pin 37 when the link 24 is swung up to dottedline position, thereby flexing the spring and lifting the pawl out ofengagement with the rack 30. In this type the spring 33. may be muchheavier and exerts more stress than the spring 35, whereby when thelever 21 is released the spring 33 tends to move thelink 24 and lever 21as an organized structure about the fulcrum 17 to dotted position,

and by reason of the engagement of the finger 36 with the pin 37 todisengage the pawl 28 from the rack 30. So that withthe return movementthe jaw'31 may' be moved with a step-by-step movement by the oscillationof the lever 21 andlink 24. A spring 38 is secured in an approved mannerto the pintle 17 as by bem inserted through said pintle, and is provi edwith a nose 39 normally engaging the teeth of the rack 30 .until thelever 31 has been swung to its disengaging limit, whereupon the nose 39is also released from the teeth of the rack, the

rack then being entirely free to be manually removed and re laced.

As shown at *igure 3, the side plates engage the jaw 18 by the use ofthe same vbolts 19 and 20. The handle 41 of this emis ivote between theside plates at 43,

an at 44 pivotally connected to the pawl 45. The spring 46 tends to movethe lever 42 to such position as to release the pawl from engagementwith the rack 30, a finger 47 and pin 48, corresponding to the finger 36and pin 37, being employed. A spr1ng 49 holds the awl 45 normally to itswork, but is adapted to be released by the movement of the lever 42 .toits dotted line position either manually or under the stress of thespring 46, the relative tension of the springs 46 and 49 being such thatthe spring 46 overstresses the spring 49.

In the type shown at Figure 3, the aw 18 is provided with a socket 50and the aw 31 with a socket 51. Either one of these sockets .50 or 51'is ada ted to receive thee punch unit 52 shown at igure 4, while theother receives the screw 53 of the mandrel used as a punch. a

. In'the modification shown at Figure 6 a more compact organization isprovided.

' The jaw 56 here shown is a shear jaw, but capable of taking any of theother forms shown in any of the other figures as sildable betweentheside plates 57. Araok 58 is carried by this jaw member and a pawl 59 ispivoted between the side plates 57 for holding the jaw member 56 inadjusted position. The jaw member 60 is connected with and operated bythe lever 61 by means of the arm 62 forming therewith a bellformation ofthe pawl is such, however, that when the pivot 65 moves forward oppositethe direction of the arrow to open the sliding jaw 60 such pivot engagesback of the paw 59 and moves such pawl against the tension of the spring66 to release its engagement with the rack 58'. Thus when the lever 61is moved opposite the direction of the arrow to its inoperative limit,the pawl is-automatically released, releasing thereby the jaw 56 formanual adjustment or replacement.

In the embodiment shown at Figure 7 a block. 68 is slidably mountedbetween t e side plates 69. A jaw 70 is also slidably mounted betweenthe side plates and provided with a rack 71. The sliding block 68carries a pawl 72 pivoted thereto at 73 with a spring 74 for holdingsuch pawl yieldingly in engagement with the rack. The lever 75 throughthe medium of the link 76 reciprocates the block 68 and therewith theawl 72 advancing the jaw 70 with a stepy-step movement, or when the jawhas come into engagementwith a body between such jaw and the stationaryjaw 76 exerting stress thereon. The pawl 72 is provided with acamshoulder 77 in position to engage a pin 78 when the lever has been movedto its ino erative limit, thereby releasing the pawl 72 trom engagementwith the rack 71.

In each of the embodiments either or both of the jaws are readilyremovable orreplaceable by any of the several types of jaws shown in anyof the several figures whereby the multiple purpose of the implement ismade available.

It will be noted also that the toggle joint connecting. thelever in theseverab types -may be secured by its oscillation.
